[Resolved] Configure the plug in properly?

I am a co-admin for a WordPress site for a client. I am trying to activate the Recent Facebook posts app. My search in the forum hasn’t helped. I believe I have correctly configured the plugin and placed the widget on the Blog page of the site. http://tuscaroramtwinery.com/blog/ It shows up there, and the link to the Facebook page is active. But there are no posts to show and this error message appears: Did you configure the plugin properly?
